Sorry about that last post; I pushed the wrong key before I was finished. My sister is being told that because she's on WC and needs two levels, she can in no way have ADR. I am trying to convince her to go with one level ADR and one level fusion instead of two levels fusion. Have you thought about that? It might be quicker and, though not ideal, less problematic for the surrounding discs in the future. My heart goes out to you.
